Lugano's air quality faces the Swiss lake basin challenge, with the city's position in the enclosed Ceresio Lake basin surrounded by Monte San Salvatore and Monte Brè creating topographic concentration of vehicle emissions from the A2 motorway and tourism traffic under frequent winter inversions. The lake breeze provides distinctive daily ventilation, while the surrounding Ticino Alps and the Italian Po Valley influence create unique cross-border air quality dynamics throughout the year.

Are air quality levels in Lugano based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
